COMBINED COAL AND GAS RANGE.

Specification of Letters Patent.

Patented Uct. 19,1915.

Application filed July 20, 1915. Serial No. 40,913.

To all whom it may concern:

Be it known that I, GEORGE E. HiaIDBREDER,

a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented a new and-useful Combined Coal and Gas Range; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as wilk enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to a combined coal and gas range, and one of the objects of the invention is to improve the combined coal and gas range set forth in George E. Heidbreders application-for patent filed March 20,1915, Serial No. 15,72

I Another object of the invention is to provide a heating space or passage upon one.

end, the bottom and the rear wall'of the oven. I

Another object of the invention is to provide a gas heating space on the lower part of theother end wall and the lower part of the rear wall of the oven, andin which case communication between the oven and the passage at one end of the oven.

' Another object of the invention is the provision of a valve, the valve stem of which has means of connection with the. slide dampersof the gas heating space and the damper which controls the opening of-com munication between the oven and said passage, whereby the gas may be turned on and the damper simultaneously opened.

Another object ofthe invention is the provision of a damper which may be opened so as to carry the products of combustion from the fire box of the range direct through the flue at the rearof the range. The 0105-,

ing of this'damper, after the fire iii the box is thoroughlyburning causes the products of combustion to pass through the passage over the top of the oven and through the passage of one end of the oven, then through the passage under the oven, making a 10 p,

then returning to another passage at t e end of the oven, and finally passing out through the passage at the rear of the oven and through the outlet'fiue. v v

In practical fields the details of'constructlon may necessitate alterations, falling within the scope'of what is claimed.

The invention comprises further features and combinations of parts, as hereinafter set forth, shown in the drawings and claimed. 1

In the drawings -Figure 1 is a front ele-.

vation of the improved combined coal and gas range constructed in accordance'with the invention, Fig. 2 is a plan View of the range, showing parts broken away, to better illustrate a damper for controlling the products of combustion in the fire box to the outlet fiue'. Fig. 3"is a sectional view on line 33 of Fig. 2. Fig. 4 is a rear elevation of the range.' Fig. 5 is a horizontal sectional view'on 'line 5-5 of Fig. 4. Fig. 6 is a vertical sectional view on line 66 of Fig. 5. Fig. 7 is a diagrammatic view'illustrating a burner, the VfllWB thereof, the slide.

damper at the rear gas heatingspace and the damper at the side gas heating space, and the means for simultaneously operating the valve and said damper, and the damper which controls the. opening of communica- 'tion between the oven and the passage at one'end thereof.

I Referring to the drawings, more espe cially, 1 designates the casing of the range, which may be any suitable shape or configuration, and is provided with a fire box 2 and ash pit 3 and the oven 4. A passage 0 extends across the top 0f the oven and merges into a passage cl between one end wallof the oven and the end wall of the range,

which passage d extends angularly and f merges into a passage 6 between the bottom of the oven and the bottom of the range.

Thispassage 6 makes a loop 9 and merges into thefpas'sage h, which. in turnmerges into anangularly arranged passage is ex-. tending upwardly between one end wall of the oven and the adjacent end wall of the casing of the range, and communicates with the passage m, which in turn merges-into'105 divides the top of the range so as to form the-outlet flue as shown at n. The Wall ;0

the passage 0 and the. space 8 for the burners tn,- 1; and a, there being an additional spa'cea in the top of the range for the burners a and a, all of which burners receive their supply of gas through the pipe a A slide damper a is provlded controlling the opening a, so as to permit air to enter the space or passage 0, where it merges into the first angularly arranged passage. The damper ahas a slot a through which a headed lug extends shown at a to guide the damper. The rod a is connected to the damper whereby the same may be operated. The rear Wall 12 of the passage 0 has. an opening 6 guides b for controlling the opening 6 A rod 2) is connected ,to the damper b as shown at b for adjusting the damper. This rod has a right angled upwardly extending part b slidable in the slot 6 in the top of the range to guide the rod as it is manipulated. The damper b is provided for the purpose of permitting the products of combustion (when a fire is first made in the fire box, or to give the fire a quick draft to cause it to burn) to pass directly out through the outlet flue. The outlet flue is designed to be connected at 9* to the range.

The lower portion of, the rear wall of the oven, and the end wall '7 of the oven at its lower portion has a gas burner heated space angular as shown, which comprises the spaces 11 and 12 in communication asshown,

at 13. The bottom 14' of the range adjacent the space 11 is provided with'elongated triangular shaped openings 15, with whichthe pivoted damper 1G coi'sperates, for controlling the fresh air draft into the space 11 of said passage, so that the burner 17 will have a proper combustion. The burner 17 consists of a perforated tube or pipe 18 extending through the space 11 of said angular space, and through the space 12 and terminates exteriorly of the range easing into theusual air cup 19, beyond which a suitable valve 20 is provided, and beyond the valve a pipe 21 may be connected to the source of gas supply (not shown). The rear wall of the oven and the end wall thereof adjacent the space .11 are provided with apertures 24 and 25 of communication between the oven and the spaces 11 and 12, so that the heat from the gas burner heated spaces will enter the oven. In lighting the burner, a lighted match may be held adjacent the apertures 24 and 25 ofthe oven wall, after turning on the gas. The bottom of the space 12 has perforations 26, and adjacent this bottom is an angular slide damper 27, which is provided with perforations or openings 28, through which, when in registration with the perforations or openings 26 air is drawn into the space 12, in order'to create the proper combustion when the burner is lighted. The greater portion of the angular slide damper is guided by the elongated slots 30 and pins 31. The end 32 of the slide damper 27 has a notch and angle end connection with the ivoted damper 16, so that when the damper 27 is operated, so as to throw the apertures A damper b is mounted in or openings 28 of the damper in and out of registration with the openings or apertures 26, the pivoted damper is oscillated, to uncover'or cover the openings 15 in order to control the intake of air into the spaces 11 and 12, in order to control the combustion of the burner. Mounted in bearings'34 of one corner of the range is a vertical shaft 35 having an arm 36 secured to it as at" 37. This arm 36 has an'eye 38, Which receives the angled end 39 of the rod 40, which is guided in the Wall of the range, as at 41 and has its end 42 connected at 43 to the damper 44, so that when the shaft 35 is rocked in one direction or the other, the damper 44 (which covers the opening-45) is opened or,

closed. When opening thedamper 44 additional heat is allowed to pass from the oven into the passage d to maintain the proper temperature in the oven. The valve 20 has a valve arm 46 extending laterally, and which arm enters the eye 47 in the end of the angular arm 48 of the vertical shaft 35. An additional arm 49 is fixed to the shaft 35 and has a downwardly extending portion 50 engaging a transverse slot 51 in an extension 52 of the slide damper 27.

Upon referring to Figs. 5 and 7 of the drawings it will be observed that by rocking the shaft 35 in the direction of the arrow 0 into registration with the openings or apertures 26. At the same time the slide damper 2Tis sooperated, the pivoted damper 16 will be oscillated to uncover the openings 15, ir order topermit the burner. to receive aproper supply-of oxygen, whereas the damper 44 is openedto permit of greater supply of heat to enter the oven.- A reverse movement of the shaft 35 will close the dampers 44, 27 and 16, and also close the valve 20.

To light the gas burner a lighted match or the like may be dropped down through the tube m which is funnel shaped at its lower end, as shown at m particularly in Fig. 4. After the gas is turned on the match or the like is dropped into the tube. thereby igniting the gas in the chamber or space 12 and space 11.
